ZHA - IKEA Styrbar - White Spectrum Lights

This Blueprint was made to control White Spectrum Lights via an IKEA Styrbar Remote connected trough ZHA.
Check out @niro1987 's awesome blueprint for the Tradfri 5 Button remote, this blueprint is based on his work and adopted to work with the Styrbar remote. Thank @niro1987!

Button Duration Action
Dim-Up short Turn on
Dim-Down short Turn off
Dim-Up long Increase brightness
Dim-Down long Decrease brightness
Right short/long Increase temperature
Left short/long Decrease temperature

Hi, can you help me with setting this up?
I have my remote connected, lights I want to control are in a group and I have set the automation to use the remote to control the lights.

Now I get following errors in the log and remote is not doing anything. I dont know how to solve this and googlefu didnt help.

Error: In 'template' condition: UndefinedError: 'dict object' has no attribute 'event'

Hey wondrej,
hmm, the ZHA Event doesn’t seem to contain the expected information.
Would you please check the content of the zha events fired by your remote?
In order to do so, go to developer tools > events, enter “zha_event” in the “listen to” text input and click on “start listening”. You should then see events popping up when pressing a button on your remote.

Hi! sorry for confusion. I thought its something wrong with the blueprint, but repairing the remote fixed all the issues.

Thank you for the blueprint, it works great!

great to hear!

Do you know how to convert this to z2m? Im new to home assistant so i cant get get it to work by myself

Hey revedar,
Have a look at the AwesomeHA Blueprint projekt: Awesome HA Blueprints | Awesome HA Blueprints

Hi Jeff, I need to use this code and apply it to a group of Ikea rgb lights, but I’m at a loss. How could I adapt it?
Thank you very much!!

Maybe this helps you:

Hi, worked first time without any issue and performed like it should. Well done, thank you for this blueprint. I’m still trying to have the controller and light work to work. Regards, Luis Sismeiro

Thank you, this was so easy to implement!
I made some changes to speed up the transitions (because I’m impatient) and to always start a specific scene instead of turning on my light group.
I could not have done it without the simplifications you have made to ZHA - IKEA TRADFRI - 5 Button Remote - Warm White Lights.

This is the best blueprint that worked with my pair of styrbar and tradfri bulbs.

I’ve made some changes to make it more customizable and fix some things that worked better for me but hopefully will work better for more people.

I’m a bit new to Home Assistant so I still don’t know all the tidbits of how to contribute to existing blueprints, so I’m pasting the full blueprint with my changes here. LMK if there’s a better way.

What changes ?

Simplified the code a bit, made the steps for brightness and color temperature configurable (both on button presses and clicks), tied the transition time to the delay (and made it configurable) as it will avoid problems on holding for longer and stacking multiple events…

I think those are what I remember. This made it almost perfect to me as the color temp still has a bit of a delay to start triggering whilst holding, but this is also true in other blueprints, so I think might be a styrbar integration issue.

I’ve made some changes on it today to work with scenes instead if anyone’s interested.

It will:

  • Clicking the turn-on button with all lights off will restore the last activated scene
  • Doing the same with at least one set of lights active, will cycle through the configured list of scenes
  • Holding on or of will decrease or increase the brightness of the lights turned on
  • Pressing left or right will increase or decrease color temperature by a big step of the lights turned on
  • Holding left or right doesn’t work well, but it was supposed to granularly increase or decrease color warmth, but it’s confusing everything at the moment.

There’s a few requirements

  • You need to have only one light group on a specific scene
  • You need to have a light group which includes all lights (to detect if any are on and to turn all of them off just in case)
